Sonic Mania Plus! coming this summer!

This summer 2018, Sonic Mania will be updated and renamed "Sonic Mania Plus!".
(I wouldn't have thought of it myself...)

What do we get in this new package? (which won't be a free update, by the way.)
Among other things, Mighty the armadillo and Ray the flying squirrel will be playable!

2 more guys added to Sonic Mania! This game is starting to lack girls! Where is Amy? Oh, I forgot, there's a mod to add her too.
